> Affects Versions: 2.1.0

> When fixing HIVE-13083 noticed that for non-null decimal values, set function does not update the isNull state (isNull[i] should be set to false). Updating this state in DecimalColumnVector breaks all decimal vector filter expressions as the filter expression can change state on it's own.
> {code}
> System.arraycopy(inputIsNull, 0, outputIsNull, 0, n);
> for(int i = 0; i != n; i++) {
> // The following may override a "false" null setting if an error or overflow occurs.
> DecimalUtil.addChecked(i, vector[i], value, outputColVector);
> }
> {code}
